Finding a factory GTO Ram Air IV or H.O. aluminum intake manifold is hard, but in most instances, if the car was used for racing, the cast-iron exhaust heat crossover and shield was tossed. If you're doing a "right-on" restoration or you want the choke to work on the Q-Jet, and you're running one of these manifolds, you have to have that crossover and shield. OPGI now has quality reproductions of both the cast-iron exhaust crossover and the two-piece heat shield to fit these manifolds.
